ATTACHMENT FOR HANDSAWS.

SPECIFICATION forming part of Letters Patent No. 648,511, dated May 1, 1900. Application filed August 29,1899. Serial No. 728,901. (NomodeL) To all whom it may cancer-1e:

Be it known that 1, JOHN G. L ons, a'citizen of the United States, residing at Cosmopolis, in the county of Ohehalis and State of Washington, have invented new and useful Improvements in Attachments for I-Iandsaws, of which the following is a specification.

This invention relates to certain new and useful improvements in attachments for handsaws, the object of myinvention being to provide the handle of a handsaw with means for blowing the sawdust away from the board or other object being sawed to remove the sawdust from a line or mark thereon.

The invention consists in the combination, wit-h a saw-handle, of an elastic bulb carried thereby, a tube which extends from the bulb toward the saw-teeth, and means connected to the tube and saw-handle for directing the blast of air as desired.

In the accompanying drawings, which illustrate my invention, Figure 1 is a side elevation of a saw, showing my improvements applied thereto. Fig. 2 is a sectional view on the line 2 2 of Fig. 1,-and Fig. 3 is a detail view showing manner of attaching the end of the tube to its guide.

The saw and handle in general outline are constructed in the usual manner, the portion of the handle which is grasped by the operator having therein a recess a, with concave ends, which is adapted to receive and retain a bulb A, of elastic material, which is shaped so as to lie within the recess and be retained therein. Through the lower portion of the handle is an opening c, and to the bulb is connected a tube 19, which passes through the opening a, one end being attached to the bulb, while the other end extends toward the heel of the saw.

Within a recess made in the saw-handle, near the lower horn thereof, is pivotally at tached bya friction-screw an arm 0, to which the tube 1) is suitably connected. This arm may carry a sleeve, into which the end of the tube It) is passed, as shown in Fig. 3.

The recess which receives the bulb may be made in either side of the handle, according to whether the person using the saw is right or left handed, and in operationthe saw is grasped in the usual manner, and when it is desired to blow away sawdust which collects upon the article which is being sawed the operator, while sawing, need only press the ends of his fingers upon the bulb, which will force a current of air out of the tube upon the article being sawed. By locating the blast mechanism in the handle the current of air is directed toward the teeth of the saw in rear of the heel of the saw, so that the sawdust is blown away from each side of the blade.

I claim-- -1. A handsaw, the handle thereof being provided on one side of its grasping portion with a recess, a bulb positioned and retained within said recess and a tube extending from the bulb toward the saw-blade, for the purpose set forth.

2. In combination with a saw-handle having a recess therein of a bulb located within said recess, a tube connected with the bulb and an arm pivotally attached to the sawhandle and connected to the tube, substanthe saw-handle, an arm adj ustably attached to the saw-handle at one end and connected to the tube at its other end, substantially as shown.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
